I was running 9.5r1.8, all I did was add a vlan member to the physcial port that's tagged to the m7i and traffic stopped on that interface.

This link connects to a gig interface on a m7i, which I have not configured the additional vlans on yet. Though 101, 501, 510, and 505 are configured on
there.

All I did was added vlan members 513, 514, 515 and commited it and that brought down all connections that pass through the 4200 interface ge-0/1/2
to the m7i.

Brendan,

Could you comment a bit more on your config with this issue?  I just
attempted to replicate it on a 9.5R2 lab box and was unable.

I tested with OSPF running on an RVI with two upstream routers.
Changing trunks unrelated to OSPF didn't flap.  Neither did changing
trunks carrying the VLAN for my RVI.

I just want to make sure I'm 100% avoiding this potential issue.
